IN CASE OF EMERGENCY INVOLVING A MAJOR SPILL, FIRE OR POISONING, CALL (FASTMED) PRODUCT INFORMATION SIERRA 2.0 Herbicide is a selective herbicide for post-emergence timings in spring wheat (hard red spring, Canada Prairie spring, soft white spring, and extra strong or utility), durum wheat, and winter wheat SIERRA 2.0 Herbicide applied post-emergence must be tank mixed with a surfactant listed on this label. For broader spectrum activity, SIERRA 2.0 Herbicide may be tank mixed with a broadleaf herbicide listed on this label. See TANK MIXES section for recommended products. SIERRA 2.0 Herbicide is absorbed by foliage and roots of wild oat, green foxtail and certain broadleaf weeds. These weeds cease growth soon after application, removing the competitive effects of susceptible weeds. However, complete weed control may not be seen for one to two weeks. SIERRA 2.0 Herbicide will control wild oat biotypes which have developed resistance to ACCase (Group 1) and triallate (Group 8) herbicides. SIERRA 2.0 Herbicide will also control green foxtail biotypes resistant to ACCase (Group 1) and dinitroaniline (Group 3) herbicides. One L jug contains enough SIERRA 2.0 Herbicide to treat 27 to 54 hectares depending on the target weeds to be controlled. For weeds controlled and staging of application for each rate refer to the recommended application tables.

5 Approved Pamphlet SIERRA Page 5 of L Jug Treats the Following: Use Rate Acres Hectares 36 ml/ha ml/ha ml/ha ml/ha DIRECTIONS FOR USE General Precautions Read the entire DIRECTIONS FOR USE before using SIERRA 2.0 Herbicide. Do not mix, load or clean spray equipment within 10 metres of well-heads or aquatic systems, including marshes, ponds, ditches, streams, lakes, etc. Buffer Zones: Overspray or drift to sensitive habitats should be avoided. A buffer zone of 20 metres is required between the downwind edge of the boom and the closest edge of sensitive terrestrial habitats including forested areas, shelter belts, woodlots, hedgerows, and shrublands. A buffer zone of 35 metres is required between the downwind edge of the boom and the closest edge of sensitive aquatic habitats including sloughs, coulees, ponds, prairie potholes, lakes, rivers, streams, wetlands, and wildlife habitat at the edge of these bodies of water. Do not contaminate these habitats when cleaning and rinsing spray equipment or containers. Consult the label of the tank mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture. Do not apply during periods of dead calm, when winds are gusty or when wind speed is greater than 15 km/h at 2 metres high above ground at the site of application. Do not apply post-emergence treatments if it is raining or if rainfall is expected within one (1) hour after application. Do not graze treated fields or use green crop for feed. Wheat grain or straw from harvested treated fields may be fed to livestock. Do not allow this chemical to drift on to other crops, especially canola, tame oats, or other non target crops. Observe minimum interval to harvest of 80 days after treatment. Do not treat wheat underseeded to legumes. Do not freeze. Ground Application Apply alone or in tank mixes in a spray volume of L/ha ( L/acre or 5 10 gallons/acre) at kpa (30-50 PSI) pressure to ensure proper weed coverage. Flat fan nozzles of 80 o or 110 o are recommended for optimum coverage. Do not use floodjet nozzle or control droplet application equipment. Nozzles may be oriented 45 o forward to enhance crop penetration and to give better weed coverage. Do not apply during periods of dead calm, when winds are gusty or when wind speed is greater than 15 km/h at 2 metres high above ground at the site of application.

6 Approved Pamphlet SIERRA Page 6 of 14 Do not apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground. Aerial Application Apply alone or in tank mixes (ONLY with the recommended tank mix partners that are registered for aerial use) in no less than 28 L/ha spray volume at a pressure that delivers medium spray droplets as classified by the ASAE. Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label. Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on this label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment. Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan. Aerial Use Precautions Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/Provincial/Territorial committee on Pest management and Pesticides. Do not apply to terrain where there is potential for surface run off to enter aquatic systems. Do not apply to any body of water. Avoid drifting of spray onto any body of water or other nontarget areas. Specific buffer zones should be observed. Do not apply during periods of dead calm. Avoid application of this product when winds are gusty or when wind velocity and direction pose a risk of spray drift. Do not apply when wind speed is greater than 16 km/h at a flying height at the site of application. Do not apply with spray droplets smaller than ASAE medium classification. Aerial Operator Precautions Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted. It is desirable that the pilot have communication capabilities at each treatment site at the time of

7 Approved Pamphlet SIERRA Page 7 of 14 application. The pilot (aerial applicator) must wear long-sleeved shirt, long pants, socks and shoes. The field crew and the mixer/loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup and repair. Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label. All personnel on the job site must wash hands and face thoroughly before eating and drinking. Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly. Product Specific Precautions Read and understand the entire label before opening this product. If you have questions, call the manufacturer at or obtain technical advice from the distributor or your provincial agricultural representative. Buffer Zones Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment. The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas, and shrublands) and sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands). Buffer Zones (metres) Required for the Method of Crop Protection of: application Aquatic Habitat Terrestrial Habitat Field sprayer Wheat Aerial Wheat Fixed wing Rotary wing Consult the label of the tank mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture. Apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners. Field sprayer buffer zones can be reduced with the use of drift reducing spray shields. When using a spray boom fitted with a full shield (shroud, curtain) that extends to the crop canopy, the labeled buffer zone can be reduced by 70 %. When using a spray boom where individual nozzles are fitted with cone shaped shields that are no more than 30 cm above the crop canopy, the labeled buffer zone can be reduced by 30 %. TIMING OF APPLICATION SIERRA 2.0 Herbicide can be applied post-emergence in all types of spring wheat (including

8 Approved Pamphlet SIERRA Page 8 of 14 durum wheat). Research has demonstrated that optimum wheat yield is obtained by early removal of target weeds prior to tillering of wheat. In post-emergence use, apply SIERRA 2.0 Herbicide to wheat that has a minimum of one leaf to a maximum of four leaves on the main stem, plus two tillers. Application beyond this stage may result in yield losses due to weed competition. POSTEMERGENCE USE DIRECTIONS IN SPRING AND DURUM WHEAT Apply SIERRA 2.0 Herbicide plus a surfactant when the majority of wheat has a minimum of one leaf to a maximum of four leaves on the main stem, plus two tillers. Use a registered nonionic surfactant such as AGRAL 90, Ag-Surf, etc. at a rate of 0.25% v/v (0.25 L per 100 L total spray solution). Do not apply more than 72 ml/ha of SIERRA 2.0 Herbicide (30 g ai/ha) per growing season.

Fill the spray tank 1/3 to 1/2 full with clean water and begin agitation or bypass. 2. Add the appropriate SIERRA 2.0 Herbicide rate directly to the spray tank. Vigorous agitation is required to dissolve the SIERRA 2.0 Herbicide. Maintain sufficient agitation during both mixing and application. 3. Add the broadleaf weed herbicide. 4. Add the surfactant, then complete filling tank with balance of water needed. SPRAYING INSTRUCTIONS Ground Application Unless otherwise specified in the tank mix partner section of this label, apply in a spray volume of L/ha ( L/acre or 5 10 gallons/acre) at kpa (30-50 PSI) pressure to ensure proper weed coverage. Flat fan nozzles of 80 o or 110 o are recommended for optimum coverage. Do not use floodjet nozzle or control droplet application equipment. Nozzles may be oriented 45 o forward to enhance crop penetration and to give better weed coverage. Aerial Application Unless otherwise specified in the tank mix partner section of this label, apply in a spray volume no less than 28 L/ha (11 L/acre or 3 gallons/acre) at no less than 300 kpa pressure to ensure proper weed coverage. Do not apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. To reduce drift caused by turbulent wingtip vortices, the nozzles distribution along the spray boom length MUST NOT exceed 65% of the wing or rotorspan. SPRAYER CLEAN-UP 1. Drain the tank and thoroughly rinse spray tank, boom and hoses with clean water. Pay particular attention to flushing out any visible deposits. 2. Fill the tank with clean water and 1% v/v (1 L/100 L) household ammonia. Flush the hoses, boom and nozzles with the cleaning solution. Circulate for at least 15 minutes. Flush

13 Approved Pamphlet SIERRA Page 13 of 14 hoses, boom and nozzles once more, then drain the tank. 3. Clean nozzles and screens in a separate container using the ammonia and water. 4. Repeat #2. 5. Rinse tank, boom and hoses with clean water. Do not clean sprayer near desirable vegetation, wells, or other water sources; Dispose of all rinsings in accordance with provincial regulations; Check tank mix partner label for any additional clean-up procedures. ROTATIONAL CROPS The following crops may be planted 11 months after an application of SIERRA 2.0 Herbicide. Soil Zones and Rotational Crops Gray-Wooded Black Dark Brown Brown Spring wheat Spring wheat Spring wheat Barley Barley Canola Canola Field peas* Field peas* Field bean Flax Flax Durum wheat Durum wheat Spring wheat Barley Canola Field peas* *Field peas may be grown the year following SIERRA 2.0 Herbicide application providing the following are all met: 1. Soil ph must be below 7.5, 2. Organic matter must be above 4%, and 3. Precipitation must be equal to or above 10 year average (minimum 100 mm within 60 days of application in year of application). Or, fields can be summerfallowed. As SIERRA 2.0 Herbicide is degraded by soil microbes, environmental conditions that decrease microbial activity must be considered when making rotational cropping decisions. These environmental conditions include prolonged drought and/or cold temperatures within the following cropping season, as well as soils with both low OM (less than 2%) and high ph (greater than 7.5). If these conditions exist, a soil bioassay may be necessary to ensure rotational crop safety. Do not plant crops other than those listed above in the year following application of SIERRA 2.0 Herbicide on wheat. RESISTANCE MANAGEMENT RECOMMENDATIONS For resistance management, SIERRA 2.0 Herbicide is a Weed Science Society of America (WSSA) Group 2 Herbicide. Any weed population may contain or develop plants naturally resistant to SIERRA 2.0 Herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.

14 Approved Pamphlet SIERRA Page 14 of 14 To delay herbicide resistance: Where possible, rotate the use of SIERRA 2.0 Herbicide or other Group 2 herbicides with different herbicide groups that control the same weeds in a field. Use tank mixtures with herbicides from a different group when such use is permitted. Herbicide use should be based on an Integrated Pest Management (IPM) program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices. Monitor treated weed populations for resistance development. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed. Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
